What truth?
You are making massive assumptions, unless you actually know something, and if you do then surely you should spill the beans.
I'm not stupid enough to think that it doesn't happen, but the way you go on about it is inferring that almost every player is doing it.
Stat, we all know that these cyclists are a breed apart.
But, and no offence mate, I find your constant comparisons of these cyclists physical attributes and also the drug testing to football rather tiresome.
